Off the top, I would suggest a fresh perspective on the skis/body relationship. While it is common to think about getting the skis out from under the body, I would suggest thinking in terms of the skis and body being on separate, yet inter-related, paths, each managed in relation to the other. The body takes a shorter shallow arced path, while the skis take a longer and more deeply rounded arc. This is most evident in falline turns where the body does not deviate from side to side. For this to happen, the legs must flex thru transition to allow ski and body paths to cross without conflict or re-direction of the body's path. The legs then lengthen as the paths separate, becoming most extended in the falline, before again beginning to flex as skis come around and back toward body for next transition.
In that most turns are somewhat out of falline and provide for some re-direction of the body path, I reference the projection, or extension of the body diagonally (or laterally) toward the inside of the turn. This is important as it leaves the integrity of the skis carving path undisturbed, compared to when you push the skis out from under body. An aggressiveness of the release of the body across the skis path toward the inside of the new turn promotes higher edge angles earlier in the turn due do a greater angle of separation of skis/body paths. [img]smile.gif[/img] This releasing of the body, by softening the legs, must start before the body path is completely re-directed across the slope which would then requires either the body to follow skis path into falline (low edge angles) or the skis to be pushed laterally out from under, a common fault
I look at the flow of energy and connection from turn to turn as being dependant on the timing of the release of the body on its path toward inside of new turn. Note, this must start before edge change for optimum energy flow and to enable the high-end turn dynamics you seek. The flexion/extension pattern is: Flex to release body down and across thru edge change, followed by lateral extension of legs as body moves inside thru falline, then timing leg flexion to control pressure and body release from falline to next transition.
If as you soften your legs to release the body earlier, you continue to roll your feet (lead by inside foot) with intensity to increase edging (creating greater lower leg angles) the skis will tighten their arc around to cross under the body path at a more radical angle yielding the above mentioned path separation in the top of the next turn.

The cornerstone skills for this level of dynamic skiing are the above described edge change with flexion (not extension) and the ability to change edges without changing direction (pivot) of skis. This latter skill is first developed doing railroad track turns (twin arc pure carves) on flatter terrain. Practice triggering each edge change/release by rolling new inside foot over toward little toe edge (or its big toe up off snow if that perspective works better) as that old outside/new inside leg is softened. This promotes the release of body across skis vs. pushing off new outside ski big toe which promotes displacement of ski out from under body and a skidded turn entry.
Hope this helps.
